1. INTRODUCTION
1.1 Review
Verify that the product and the packing does not indicate
any signs of damage. If there are signs of such, please
contact your distributor immediately.
1.2 Description
The ST 007 will test the socket wiring and will indicate
exactly each of the faults in the wiring system.
The ST 007 will check existence of RCD and if the RCD is
damaged.
Note: The ST 007 does not check the earth loop
impendence which is a necessary test. To perform this
test, you should use a Loop tester device. You can find
this devise and many other testers
in our website: www.itestp.com
1.3 Health & Safety
Health and Safety regulations require that electrical
installations will be checked periodically for satisfactory
operation. The presence and quality of the wiring and of
the protective device such as RCD is crucial part of the
check. Increasingly, protective devices (RCD’s or RCBO’s)
are used for the Earth circuit, just as fuses or breakers
are used in the Live circuit. These RCD’s can be sensitive
to test currents used during a temporary measurement
link and trip out easily, which can cause both nuisance
and loss of data in computer systems. More modern
electronic protective devices are particularly sensitive,
even being tripped out by instruments which were usable
with the earlier electro - mechanical types.
